Operation Argus was a series of United States low-yield, high-altitude nuclear weapons tests and missile tests secretly conducted from 27 August to 9 September 1958 over the South Atlantic Ocean. [ 1 ] [ 2 ] The tests were performed by the Defense Nuclear Agency .
The US's first national laboratory, Los Alamos was created secretly during World War II to build the first nuclear weapon. During the 1958 moratorium on nuclear testing, a number of sub-critical tests were performed underground to learn more about the dynamics of explosions and the metallurgy of plutonium.

High-altitude nuclear explosions are the result of nuclear weapons testing within the upper layers of the Earth's atmosphere and in outer space. Several such tests were performed at high altitudes by the United States and the Soviet Union between 1958 and 1962. The Partial Test Ban Treaty was passed in October 1963, ending atmospheric
A map claiming to show the areas of the US that may be targeted in a nuclear war that originally circulated in 2015 is making the rounds again, amid the Russian war in Ukraine.
On August 1, 1958, Redstone rocket launched nuclear test Teak that detonated at an altitude of 77.8 km (48.3 mi). On August 12, 1958, Redstone #CC51 launched nuclear test Orange to a detonation altitude of 43 km (27 mi). Both were part of Operation Hardtack I and had a yield of 3.75 Mt
